DATA READ METHOD, DATA WRITE METHOD, DEVICE, AND SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18147950 titled 'DATA READ METHOD, DATA WRITE METHOD, DEVICE, AND SYSTEM

Simplified Explanation

The abstract describes a data write method for a computer device with a non-uniform memory access architecture (NUMA) system. It involves obtaining a write request for target data, determining the target page in the storage device that stores the data, selecting a target buffer from the nodes' buffers, writing the data into the target buffer using a controller, and finally writing the data from the target buffer into the target page in the storage device.

• The data write method is designed for a computer device with a non-uniform memory access architecture (NUMA) system.
• The computer device includes a storage device and multiple nodes, each with a buffer and a controller.
• The method involves obtaining a write request for target data.
• It determines the target page in the storage device that stores the target data.
• It selects a target buffer from the buffers of the nodes.
• The target data is written into a page of the target buffer using a controller.
• Finally, the data from the target buffer's page is written into the target page in the storage device.

Potential Applications

• This technology can be applied in computer systems with non-uniform memory access architectures (NUMA) to efficiently write data.
• It can be useful in high-performance computing systems where data needs to be written and accessed quickly.

Problems Solved

• The data write method addresses the challenge of efficiently writing data in a computer device with a non-uniform memory access architecture (NUMA) system.
• It solves the problem of determining the appropriate buffer and controller to use for writing data into the storage device.

Benefits

• The method allows for efficient writing of data in a computer device with a non-uniform memory access architecture (NUMA) system.
• It ensures that the data is written to the correct target page in the storage device.
• By utilizing the buffers and controllers of the nodes, it optimizes the data writing process and improves overall system performance.

Original Abstract Submitted

A data write method, a data read method, a device, and a system are provided. The data write method is applied to a computer device, which includes a storage device and a plurality of nodes in a non-uniform memory access architecture (NUMA) system, and each node has a buffer and a controller that controls the buffer. The data write method includes: obtaining a write request of target data; determining, in response to the write request, a target page that is in the storage device and that stores the target data; determining, from a plurality of buffers corresponding to the plurality of nodes, a target buffer corresponding to the target page; writing the target data into a page of the target buffer by using a target controller that controls the target buffer; and writing data of the page of the target buffer into the target page in the storage device.
